The invention relates to a multi-mode gearbox, a hybrid power system and a vehicle, and belongs to the technical field of hybrid power systems. According to the scheme, on the basis that an engine and a motor are coupled through a planet row and output through a multi-gear transmission at the downstream, a gear shifting mechanism is additionally arranged at the input end of the planet row, the gear shifting mechanism can achieve transmission connection of the two input ends of the planet row, and the whole planet row rotates synchronously; the output end of the planet row is directly connected with the output shaft in cooperation with a downstream gear shifting mechanism, 1: 1 direct driving from the first input end to the output shaft is achieved, and a high-speed gear mode with high efficiency and low transmission loss is achieved; meanwhile, when one input end of the planet row is locked through the added gear shifting mechanism, the planet row outputs power input by the first input shaft at the other speed ratio, and when the planet row has two output speed ratios of 1: 1 direct output and non-1, the number of driving modes is doubled in cooperation with a plurality of gears in the downstream multi-gear transmission, and therefore the driving efficiency is improved. And more subdivided working conditions can be efficiently adapted.
本发明涉及一种多模式变速箱、混合动力系统及车辆,属于混合动力系统技术领域。该方案在发动机和电机通过行星排耦合并在下游通过多挡变速器输出的基础上,在行星排输入端增加换挡机构,该换挡机构能够实现行星排的两个输入端传动相连,使整个行星排同步转动,再配合下游换挡机构将行星排的输出端与输出轴直接相连,实现第一输入端到输出轴的1:1直接驱动,实现一种高效率、低传动损耗的高速挡模式;同时该增加的换挡机构将行星排一个输入端锁止时,行星排以另一个速比将第一输入轴输入的动力输出,在行星排具有1:1直接输出和非1的两种输出速比时,配合下游多挡变速器中若干挡位,将驱动模式的数量增加了一倍,能够高效适配更多细分工况。
